Abstract: Изобретение относится к устройствам для защиты от шума и может быть использовано в зданиях и сооружениях для обеспечения нормативного акустического режима, в частности в мероприятиях по звукопоглощению в производственных и жилых помещениях, в защитных экранах для оборудования, являющегося источниками шума, в придорожных шумозащитных экранах и других звукопоглощающих конструкциях. Технический результат - увеличение коэффициента звукопоглощения панели. Предлагается звукопоглощающая сэндвич-панель, состоящая из двух листовых наружных облицовок, одна из которых сплошная, звуконепроницаемая, а другая облицовка имеет сквозную перфорацию в виде отверстий для прохождения через них внутрь панели звуковых волн. Внутри панели находится массив звукопоглощающего материала в виде зафиксированных приклейкой к облицовкам ламелей из минеральной ваты, направление волокон в которых перпендикулярно плоскостям наружных облицовок. Звукопоглощающий массив состоит из чередующихся выступающих и западающих элементов ламелей разной высоты, плотно прижатых друг к другу без зазоров, создавая акустические ловушки. Ламели нарезаны из стандартных минераловатных плит и имеют наклон поверхностей граней к перфорированной облицовке сэндвич-панели в интервале от 0° до 65°, т.е. могут иметь грани от параллельного расположения относительно перфорированной облицовки до отличного от параллельного в различном их сочетании для всего массива звукопоглощающего материала. Из-за разности в высоте ламелей, составляющих массив звукопоглощающего материала сэндвич-панели, к перфорированной звукопроницаемой плоской облицовке сэндвич-панели приклеиваются только выступающие на одинаковую высоту из массива звукопоглощающего материала грани ламелей большей высоты.

Abstract: FIELD: oil industry. 
     SUBSTANCE: invention relates to the oil industry. The method for development of a layer-by-layer-zonal-heterogeneous deposit of super-viscous oil or bitumen includes determination of productive strata in the reservoir, separated by low-permeable layers, drilling in the lower stratum above the oil-water contact of a horizontal well with additional ascending boreholes opening the upper strata, the distance between which is determined taking into account the technological capabilities of the drilling equipment for their wiring, as well as with the possibility of placing filters with adjustable transmission, run down into a horizontal well before pumping a coolant on a pipe string and located opposite additional ascending boreholes, as well as packers that isolate the annular space of a horizontal well between additional ascending boreholes and above filters, determination of physical and chemical properties, injection of coolant and product withdrawal. After crossing and exiting additional ascending boreholes into the upper productive layer, they are carried out 10-40 m long along the low-producing layer, casing additional ascending boreholes and the main horizontal wellbore, running tubing into the well with couplings pre-installed opposite the side ascending intervals for pumping the coolant. In this case, first, a coolant is pumped with an intensity of 90-120 tons/day. After the injection is stopped, the well is left for thermocapillary impregnation for 35-40 days. After thermocapillary impregnation, the well is transferred to fluid extraction, the change in temperature and water cut of the produced product is monitored. When the temperature of the produced product drops to the boundary temperature of 30-40°C or when the water cut of the product rises to 96-99%, the injection of the coolant is resumed. The coolant is pumped in the volume of the sampled liquid, the pumping and withdrawal cycles are repeated. 
     EFFECT: increasing the efficiency of reservoir development, involving in the development of thin pay strata less than 10 m thick, complicated by impermeable layers, while reducing material costs.

Abstract: FIELD: metals processing. 
     SUBSTANCE: invention relates to the processing of metals by pressure and can be used to obtain turbine disks with blades by hot stamping. The workpiece, made according to the shape and size of the disk part of the blisk with an annular rim on the periphery, is heated to the temperature of plastic deformation and installed in the cavity of the sectional matrix. The central part of the workpiece is fixed between two pressure discs. Two punches apply a force to both ends of the blank's annular rim. In the closed cavity between the semi-matrices and the disks, a two-sided upsetting of the rim is carried out. Blisk blades are formed by radial extrusion of metal from the rim area in the cavity between the matrix sections. At the same time, the central part of the original workpiece is simultaneously clamped, applying a force proportional to the force on the punches to both clamping discs. After the end of the deformation, the punches, the pressure discs and the upper half-matrix are taken back to their initial position and the finished forging is pushed out of the matrix together with the sections. 
     EFFECT: possibility of using press equipment of lower power is provided and the quality of the parts obtained is improved.
